Tool UIs are Swing form-based and not Codename One API based

[liannacasper]

Create CN1 equivalents for Swing simulator tools and run them inside the host isolate.

1. Add a simulator-host CN1 package with Forms for:

   • Network Monitor
   • Component Inspector
   • Test Recorder

2. Mirror existing behavior from:

   • NetworkMonitor.java
   • ComponentTreeInspector.java
   • TestRecorder.java

3. Use design system assets under docs/design and CSS theme pipeline for simulator-host UI.

4. Keep old Swing tools behind a feature flag (cn1.simulator.hostUI=swing|cn1) for phased rollout.
